My AC started acting up last night. The fan will not shut off even when the thermostat 3-way switch (Cool-Off-Heat) controller is in the "OFF" position.
If I place it in the "Cool" position the air conditoner compressor kicks in and it cools my 5th wheel but doesn't shut off. It also just kicked out the breaker, but when the breaker was reset, the compressor kicked in again and the unit has continued to cool the RV for 40 minutes now, dropping the temperature from 78 to 71. When the compressor kicks out, the fan remains on.
Is there anyone out there with some experience similar to this? Is it more likely to be the thermostat or the AC unit (board?). The RV is a 1995 Holiday Rambler with a 13500 Dometic AC unit.
